Relationship with OpenClaw Ecosystem

The Perplexity API provides unique search-enhanced capabilities for OpenClaw agents. By integrating the Perplexity API, OpenClaw agents can search for real-time information and obtain accurate answers with cited sources when needed. This is particularly valuable for agent tasks requiring the latest data (e.g., market research, news analysis, competitor investigation). Perplexity's Search API can be used as a "web search tool" for OpenClaw agents.
